Artemisia tilesii is a species of flowering plant in the aster family, Asteraceae. Its common names include Tilesius' wormwood, Aleutian mugwort, and stinkweed. It is native to Russia, Japan, and northern North America, including Canada and the northwestern United States.
This species is a perennial herb growing from a tough rhizome. It produces one to three stems up to 80 centimeters in maximum height. The stems may be white with a coating of woolly hairs. The leaves and inflorescences are quite variable, and the species is sometimes divided into several subtaxa based on these differences. The leaves are often bicolored white and green with the distribution of hairs on the surfaces. The inflorescence may be small and compact or wide, open, and branching. Each bell shaped flower head is about half a centimeter long and lined with purplish phyllaries. It contains many yellow flowers.
The cultivar 'Ciaggluk' was developed in Alaska for use in revegetation and erosion control. It tolerates a range of soil pH and can grow on waste land made toxic by mining operations. It is easy to grow and attractive. Caiggluk is the Yupik name for the wild plant.
This plant has a number of historical uses in the traditional medicine systems of Alaska Native peoples. It has been used to treat fever, infection, tumors, arthritis and other joint pains, bleeding, congestion, and tuberculosis, and as a laxative and general tonic.
